It's not that Congressional Republicans are stupid (although, clearly, many of them are, kindly, challenged.) It's that they think you're stupid. So sure of it are they, in fact, that they've had this to say. Expect it to become the central talking point henceforth. Expect it to be all over Fox "news" until November 2012:
On Fox News today, House Rules Committee Chair David Dreier (R-CA) contended the GOP deserves all the credit for recent economic growth.
"[W]e can get our economy growing. And we've gotten some positive numbers. I think it's in large part because we won our majority and we're pursuing pro-growth policies," he said.
I'm certain he said it with a straight face, too. In the majority in the House for, like, a couple of weeks, not having passed into law a single piece of legislation, and, by golly, unemployment dropped. Never mind the turnaround began over a year ago. Never mind that they voted against all of Obama's initiatives, and predicted disaster.
